Abstract: A jigsaw includes a jigsaw main body, a handle, and a battery. The jigsaw main body includes a housing, a motor disposed inside the housing, and a battery mounting portion having a first mounting surface facing downward. The handle is disposed at an upper portion of the jigsaw main body and above the motor. The battery has a second mounting surface and supplies the motor with an electric power. The battery is slidable along the first mounting surface and mountable to the battery mounting portion with the first and second mounting surfaces facing each other.

Abstract: A portable band saw has a substantially equally balanced weight in the lateral direction. The portable band saw includes a battery mount to which a battery is attachable, a motor driven with electric power from the battery, a band saw blade being endless and rotatable with power generated by the motor, a body supporting the motor and the band saw blade, and a handle including a support connected to the body and extending in a vertical direction, and a grip connected to the support and extending in a front-rear direction. The motor has a center on one side of a center of the handle, and the battery has a center on another side of the center of the handle in a lateral direction.

Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion.

Abstract: A jigsaw includes a housing, a motor, a blade, a roller holder and a dust collection passage. The housing accommodates the motor. The blade driven by a motor protrudes downward from a front part of the housing and moves in a reciprocating manner to cut a workpiece. The roller holder is pivotally arranged under the housing and holds a roller that is arranged between a pair of side walls facing each other. The roller abuts on a rear part of the blade. The dust collection passage formed through the housing has a dust collection port that opens behind the roller holder. The jigsaw further includes a dust collection nozzle that has a vertically long opening formed on a front face and a rear face thereof respectively, the opening on the front face being connected to the dust collection port.
